Nickel oxide (NiOx) due to its p-type nature has considerable potential as a photocathodic
material in energy conversion devices such as dye-sensitized solar cells (DSSCs). However,NiOx has not been extensively used for ...

We report a TD-DFT study of three polyene dyes namely: NKX-2553, NKX-2554 and NKX-2569 in isolation as well as upon their adsorption on TiO2 nanoparticles. By choosing closely related dyes we wish to focus on the effects ...

In today’s society there is a vast and in many cases not fully appreciated dependence on electrical power for everyday life. Furthermore, with growing energy and environmental concerns arising due to fossil fuel depletion ...

In this study the use of microwave plasma sintering of nickel oxide (NiOx) particles for use as p-type photoelectrode coatings in dye-sensitized solar cells (DSSCs) is investigated. NiOx was chosen as the photocathode for ...

At present there is a global concern of environmental issues and future energy supplies, for instance global warming and the rapid depletion of fossil fuels. This trepidation has initiated a more critical investigation ...

The temporal response of a biomimetic dye-sensitized solar cell (DSSC) is critically linked to the intensity of the incident light. When a DSSC is partially illuminated and the incoming light is of low intensity, the ...

With growing energy and environmental concerns due to fossil fuel depletion and global warming there is an increasing attention being attracted by alternative and/or renewable sources of power such as biomass, hydropower, ...
